What HP motor do I need for my Goodman unit?

My AC fan is not spinning. What part do I need?

A fan that does not spin, spins slowly, or makes grinding or squealing noises needs a new motor. Grinding means the bearings have failed. Squealing means the bearings are dry. No spin with a humming sound means the capacitor may be the issue. Check the motor capacitor before replacing the entire motor.

Goodman B13400252S Condenser Fan Motor — 1/6 HP

Restore proper airflow and heat rejection with the genuine Goodman B13400252S 1/6 HP condenser fan motor, a direct-fit replacement for the Goodman GMT090-3 and compatible units. This motor drives the outdoor fan that pulls heat across the coil — when it fails, the system overheats, trips on high pressure, or stops cooling entirely. Installing the correct OEM motor brings the unit back to spec and protects the compressor from damaging heat buildup.

Specifications

Horsepower: 1/6 HP
Application: Condenser (outdoor) fan motor
Fits: Goodman GMT090-3 and compatible units
Type: Sealed ball/sleeve bearing, weather-rated
OEM Part Number: B13400252S

OEM vs. Generic

The OEM Goodman B13400252S matches the original shaft size, rotation, mounting, and electrical characteristics exactly — no adapter kits or guesswork. Generic "universal" motors often require rewiring, capacitor changes, and bracket modifications, and rarely match the original's quiet, balanced operation. OEM ensures a clean, reliable install.

Installation Difficulty

Moderate (3/5). Plan 45–60 minutes. Requires disconnecting power, removing the fan grille and blade, transferring the blade to the new shaft, and matching the wiring/capacitor connections. Comfortable DIYers can handle it; if you're unsure about capacitor discharge or wiring, a qualified HVAC tech is recommended.

How do I replace the condenser fan motor on my Goodman GMT090-3 — B13400252S?

Step 1: Turn off breaker. Step 2: Note motor specs: HP, RPM, voltage, rotation direction. Step 3: Remove old motor from mounting. Step 4: Transfer fan blade to new motor. Step 5: Mount new motor, reconnect wiring. Step 6: Restore power, verify rotation direction.

My AC fan isn’t spinning. What part do I need?

Fan not spinning, spinning slowly, or making grinding/squealing noises = motor failure. Grinding = bearings failed. Squealing = bearings dry. No spin + hum = check the motor capacitor first before replacing the entire motor.

Is this condenser fan motor compatible with Bryant or Payne too?

Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my Goodman condenser fan motor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
